A ladder 25 feet long is leaning against a wall such that it touches 24 feet high window. How far is the foot of the ladder from the wall?

24.5 feet 12 feet 9 feet 7 feet

7 feet

Height of window, P = 24 ft. Length of Ladder, H = 25 ft. Foot of the ladder, B = sqrt[ \( {25}^{2} \) - \( {24}^{2} \) = sqrt(625 - 576) = 7 ft The correct answer is Option (4) → 7 feet
